Bootstrap provides the ability to create headers within dropdown menus, which enhances the clarity and organization of your website's navigation. Headers serve as titles or categories that group related dropdown items together, making it easier for users to quickly locate what they are looking for and comprehend the structure of the menu.
Syntax:
<li>
<h6 class="dropdown-header">
Header Text
</h6>
</li>
Approach:
- Include Bootstrap CSS in the <head> section of your HTML file.
- Create a dropdown button and a dropdown menu structure using Bootstrap classes.
- Inside the dropdown menu (<ul>), add <li> elements with <h6> elements having the class dropdown header.
- Include Bootstrap's JavaScript bundle at the end of your HTML file to enable dropdown functionality.
